the first thing that happens when you breathe in is your rib cage rises and expands out. this gives your lungs room to inflate. then your diaphragm pulls down, causing air to rush from a high concentration into your lungs. (low concentration) as the air is sucked in your lungs inflate
because the lungs can not re-inflate themselves
Yes, but only when you breathe in. when you breathe out, they will deflate.
There are no muscles in the lungs that help inhale or exhale, this is the job of the diaphragm.
inhalation
Action of the diaphragm causes healthy lungs to inflate in whole like a balloon.Doctors have said that the average person does not breath properly, thereby not filling our lungs with sufficient air to help purify our blood. We should do daily exercises of deep beathing or get into the habit of breathing more deeply than we do.
ribs and bones
The diaphragm is a thin band of muscle under the lungs. When it contracts, the lungs are pulled up and out, reducing the air pressure and causing oxygen to be drawn in. When the diaphragm relaxes, the carbon dioxide is pushed out of the lungs.
To inflate the balloon. Whether the gas is helium or just air from your lungs, gases are needed to inflate the balloon.
Respiration involves the lungs. The lungs inflate with air, and this allows oxygen into the lungs. The windpipe and mouth and nose are also involved in respiration.

They get bigger, then smaller. Yup, pretty much. P.S the person who wrote this is stupid...The lungs inflate then deflate XD
It allows the lungs to inflate and deflate without the "walls" sticking to each other, acting as a lubricant.
